Product Description

Signia Silk Charge and Go IX — Full Product Overview

Overview

The Signia Silk Charge and Go IX stands out as the smallest rechargeable, ready-to-wear completely-in-canal (CIC) hearing aid available today. Debuted toward the end of 2023 and showcased at CES 2024 — where it earned a Best of Innovation Award — this device is built on Signia’s advanced Integrated Xperience (IX) platform. It caters specifically to individuals experiencing mild to moderate hearing loss. Among the very few invisible hearing aids offering built-in rechargeability, the Signia Silk Charge and Go IX continues a legacy that even royalty has embraced in earlier generations.

Design and Appearance

The Signia Silk Charge and Go IX fits entirely within the ear canal, making it virtually undetectable to others. It comes in two faceplate finishes — Mocha and Black — and features a soft, textured exterior that minimizes light reflection for added discretion. The faceplate has no battery door, resulting in a sleeker look and improved resistance to moisture, dust, and debris. With an IP68 waterproof rating, the Signia Silk Charge and Go IX is the first CIC hearing aid to achieve this level of protection. Remarkably, its dimensions remain nearly identical to the earlier non-rechargeable Silk X model — a notable engineering milestone.

Fit and Comfort

Designed for on the point use, the Signia Silk Charge and Go IX uses EarWear 3.0 ultra-soft silicone sleeves that provide comfortable once its out of the box. Multiple sizes and styles of pre-fitted click-sleeves are included, eliminating the need for custom ear impressions or lengthy fitting appointments. For those who prefer a more tailored experience, custom earmold options are also available. Additionally, Own Voice Processing (OVP) technology helps users adapt by reducing the artificial sound of their own voice during the initial wearing period.

Battery and Charging

A single charge of the Signia Silk Charge and Go IX delivers up to 28 hours of use, with a full recharge completed in roughly 4 hours. The device comes paired with a compact portable charging case that doubles as a power bank, capable of providing up to four additional charges on the go. The case supports both wireless Qi charging and conventional wired charging for added convenience.

Sound Processing Technology

The Signia Silk Charge and Go IX incorporates several advanced audio processing features:

• Dynamic Soundscape Processing 3.0 — Analyzes acoustic data, noise levels, and signal-to-noise ratios, processing up to 192,000 data points per second to continuously track multiple voices in shifting environments.
• Binaural OneMic Directionality 2.0 — Despite having a single microphone per ear due to the CIC form factor, both hearing aids share data to maintain a focused directional listening pattern, prioritizing speech from the front.
• SpeechStabilizer — Maintains the natural characteristics of speech even in demanding, noisy conditions.
• Speech and Noise Management — Reduces listening fatigue through intelligent sound filtering.
• e2e Wireless 4.0 — Handles binaural synchronization, CROS/BiCROS compatibility, and a wide range of audio features.
• Extended Bandwidth — 12 kHz processing bandwidth for improved high-frequency sound clarity (7IX tier only).
• Auto EchoShield — Automatically minimizes the impact of reverberation and sudden loud sounds (7IX only).
• SoundSmoothing™ — Softens abrupt, jarring impact sounds such as clattering dishes.
• eWindScreen™ — Suppresses outdoor wind noise interference.
• Extended Dynamic Range — 117 dB input with 24-bit processing for accurate reproduction of both quiet and loud sounds.
• Feedback Cancellation — Real-time monitoring and suppression of feedback across individual processing channels.

Connectivity and User Control

The Signia Silk Charge and Go IX is compatible with the Signia App on both iOS and Android, enabling remote adjustments and personalized sound tuning via high-frequency coded signals rather than Bluetooth. TeleCare functionality allows users to connect remotely with hearing care professionals through text, phone, or video. An optional miniPocket keychain remote is also available for those who prefer physical controls. It’s worth noting that the Signia Silk Charge and Go IX does not support direct Bluetooth audio streaming, so music and phone calls cannot be transmitted directly to the device.

Tinnitus Management

For users dealing with tinnitus, the Signia Silk Charge and Go IX offers several therapeutic options:

• Ocean Waves Therapy Signal — Four preset soundscapes inspired by ocean sounds to provide relief.
• Static Therapy Signal — Up to 20 channels and 5 preset gentle noise options, varying by model tier.
• Notch Therapy — Signia’s proprietary tinnitus solution, particularly effective for tonal tinnitus (available from 2IX tier and above).
• Tinnitus Noise Therapy Manager — Offers a choice between traditional noise therapy, amplified notch therapy, or a blended approach.

Fitting and Customization

Audiologists fitting the Signia Silk Charge and Go IX have access to a robust suite of professional tools, including up to 48 processing channels (7IX), configurable hearing programs, HD Music Programs, CROS/BiCROS support, Frequency Compression, Smart Optimizer, Data Logging, Acclimatization Manager, InSituGram threshold measurement, and AutoFit™ — which automatically generates an optimized real-ear insertion gain without manual adjustment, significantly streamlining the verification process.
